Evga 560ti 2GB Overclocking Questions

[Jotunkaiser]

Hiya, I'm just intrested to know if anyone has the same card and if so what kind of stable clock do you have.

I have been trying for a while now after reading on the net about how to do it, so Ive just been increasing it by incriments of 25 each time, and running heaven/furmark to get an idea if I'm getting an increase.

Can anyone explain to me why I would suffer a loss of score/performance with higher settings? even though I dont get any artifacting etc it seems stable but with higher settings I'm getting a lower score.

My settings atm are 870/1740/2060.

I do know I can go further but when I did push it abit more I lost score/performance although nothing looked out of place.

Anyway any advice on what I'm doing / if iam doing something wrong would be greatly apprecaited, Thank you in advance - I just want to push my card abit further towards a stable overclock and get the best I can out of it.

It's likely not stable enough to crash, but unstable enough for performance to suffer/vary. You've probably found the limit using the preset voltage for the card. Using the EVGA Precision software, you can bump the voltage up to see if that helps stability and perhaps lets you overclock a little bit further. Once you run into the same type of barrier after providing it more voltage, you'll then be temperature limited.

I have the OCUK 2GB cards.

Increasing the voltage from 1.000 to 1.050V give me a stable 950Mhz OC

1.025V is good for 880-900

You may need to check the case temps as well as the cards will throttle if too hot.

My EVGA 560Ti 1GB using the EVGA Precision Software will allow 1000 core 2275 Memory on 1.1v and is stable for benchmarking. I usually drop the voltage and core/mem speeds a notch for 24/7.

Great cards though!

Anyone know what's regarded as the safe limit for voltage 24/7 on 560Ti cards?

I can't say what is 24/7 safe; no doubt the politically correct safe 24/7 voltage is 1.000v. Consider that no one around here has yet to post about burning up their gtx 560 ti using EVGA Precision or MSI Afterburner at any voltage setting, but my bet is on 'less than 1.1v'.

Thanks, I'm at 1v now and stable with these settings 925/1850/2100 I will play around abit more and see what I can do lol.

Anyone having problems with going full screen on things like youtube etc? I have to open/close then reopen for it to work and it seems really laggy - but to solve the display driver issue I updated to the beta drivers 290.53 I think they are.

Also when my computer screen saver goes to come on - If i'm watching a movie or something it blue screens - giving some Kernel power error, I cant really make head nor tail of the event viewer, idk what to look for or post for more info
